A Application filed January 30,1882. (Model.)

10 all whom it may concern Be it known that we, WILLIAM N. WHITE- LEY and JOHN R. THOMAS, of Springfield, county of Clarke, State of Ohio, have invented a new and useful Improvement in Self-Binders, of which the following is a specification.

Fig. 14 is an elevation of the stripping mechanism and the mechanism employed to move the gripper and cutter in and out longitudinally. Fig. 15 is a partial sectional elevation of the main gear-wheel, illustrative of the device employed for throwing it in and out of gear with the continuously-running pinion of the harvestingmachine; and Fig. 16 is an end elevation, portions of the frame being omitted to show the compressing and other mechanism.

Our invention relates to self-binders that compress the grain into sheaves of uniform size, that automatically connect the binding mechanism with the harvesting mechanism, and that encircle the sheaf with a band and eject it from the machine to the ground without the aid of manual labor; and it consists in the construction and combination of devices, hereinaftcr described and claimed, for automatically binding grain.

To enable others skilled in the art to make and use our invention, we wili proceed to describe its construction and operation.

In the accompanying drawings like numbers represent corresponding parts in each of the figures.

The mechanism com posing the binder proper is mounted in a frame, 1 and 2, that may be adj ustabl y connected to any desirable harvesting-machine in a suitable manner to adapt it to both long and short grain. As the grain is transferred from the harvester to a chute, 3, it comes into the path of a revolving packer, that gradually transfers it to and packs it against a spring compressor-arm, 3, until a sufficient quantity has accumulated to form a sheaf of the desired size, at which time the compressor-arm will retreat a sufficient distance to automatically connect the binding mechanism, which has remained at rest during the formation of said sheaf with the continuously-running harvesting machinery.

. Thepacking device is composed of a series of arms, .4. and 5,secured to crank-shafts 6 and 7, that are controlled by friction-rollers 8 and 9, journaled to the cranks 10 and 11. These friction-rollers ride upon an irregular-shaped cam, 12, and are guided by a yoke, 13, that moves with and gives to them a fixed relative position. The shafts 6 and 7 are jonrnaled in arms 14. and 15, that are secured to a shaft, 16, deriving its motion from a sprocket-wheel, 17, through the agency of a chain-belt, 18, and a continuously-running sprocket-wheel, 19. The sprocket-wheel 19 is secured to the same shaft as the sprocket-wheel 20, that derives its motion from the. running-gear of the harvestingmachine.

The chute 3 is composed of a curved sheetmetal piece, 21, and the curved pieces 22, that projectabove the binding-table 23. The metal piece 21 is provided with slots 24, through which two sets of the packing-arms 4 and v5 work. The sheet-metal piece 21 prevents the grain from escaping in an upward direction and prevents entanglement of grain with packers, and the raised projections 22 serve to elevate the grain from the binding-table, so that the packers may be better able to act upon it. The main gear-wheel 25 is provided with a movable section of teeth, 26, that may be moved in toward the center of said wheel in a suitable manner to make a gap in its teeth, and thereby disconnect it from the continuouslyrunning pinion 27, fromywhich it derives its motion. This movable section is provided with a sliding head, 28, moving in ways 29, a spring, 30, and an inclined cam-track, 31.

The compressor-arm 3 is hinged to the free end of an arm,'32, that is fast to a rock-shaft, 33, upon which is secured an arm carrying a cam-track, 34, that is provided at one end with a recess, into which a friction-roller, 35, may fall when the binding mechanism is required to be at rest. to one end of a pivoted lever, 36, the other. end of which is controlled by aspriug, 37, act ing against a bolt, 38, to which said end is attached. compressor-arm outwardly, and the shaft 33 is rocked thereby, as is also the cam-track 34, and the friction-roller 35 is forced from the recess formed in one end of the cam-track 34, and rides upon the regular and even surface of said cam-track, thereby forcing back the bolt 38 and permitting the spring to force the movable teeth 26 into mesh with the pinion place the band around the sheaf.

27, and thus unite the binding with the barvesting mechanism. The main gear-wheel 25, through the agency of a pitman, 39, connecting with an arm, 40, that is secured to a shaft, 41, oscillates the binding-arm 42, causing it first to move toward thecompressor-arm 3 to assist in the compression of grain, and also to A segmentgear, 43, is also attached to the shaft 41, and consequently moves simultaneously with the binding-arm, and through the agency of a connecting-rod, 44, that connects with the packercain 12, elevates said cam to a position illustrated by Fig. 6 of the drawings, thereby causing the packers 4 and 5 to rotate in a space above the incoming grain during the operation of binding.

Previous to starting the binding-machine in practical operation one end of the band is held by a combined gripper and cutter, 45, and the band is stretched from this gripper to the point of the binding-arm located below the binding-table 23 in such a manner that said band will lie across the path of the grain as it is forced by the packers against the compressorarm, and in this manner the grain is partly encircled. by a band previous to the upward movement of the binding-arm to complete the encircling of the sheaf with said band.

The compressor-arm 3 is pivoted at 46 to an The friction-roller is attached The accumulation of grain moves the arm, 32, that is secured to a shaft, 33. The extension 47 of the arm 3 is provided with a spring, 48, that lies between it and a vertical projection, 49, that forms a part of the arm 32. To keep the spring 48 in position we fit its two ends into recesses, one of which is formed in the extension 47 and the other in the vertical projection 49. As an additional security we employ a rod, 50, that passes loosely through the center of the spring 48, also through the extension 47 and vertical projection 49. To the bottom end, 51, of the compressor-arm 3 we pivot an auxiliary and yielding 'arm, 52, provided with a spring, 53, and a retainingrod, 54 to hold said spring to its place. The spring 48 permits the arm 3 to yield under undue pressure, and thus prevent breakage. The spring 53, attached to thearm 52, performs a similar duty. The spring 48, in addition to performing the above specified function, also permits the arm 3 to oscillate in a limited space upon the pivot 46 while the packers 4 and'5 are forcing grain against it, and when the bundle is discharged returns it to its normal position. The auxiliary arm 52 is so shaped and located as to materially assist in the formation ofa round sheaf.

The knotting device is of that kind known as a knot-tying bill, and it consists of a vertical shaft, 55, provided with a horizontal hook, 56, grooved in the direction of its length to receive a tongue, 57, that is pivoted to said book. The tongue 57 is provided with a heelextension, slotted at 59 to receive a pin forming a part of a vertical rod, 60. The top end of the rod 60 is provided with two collars, 61 61, between which an extension, 62, from a friction-roller, 63, is loosely fitted. Between the lower collar, 61, and the upper end of the shaft 55 there is a spring, 64, that forces the roller 63 against a cam-track formed around the interior of the rim of the disk 65. A pinion, 66, is firmly secured to the shaft 55, and a section of teeth, 67, forms a part of the disk 65. This section 67 has as many teeth (less one) as the pinion 66, and at the proper time actuates said pinion just one revolution, startingtoward theinner side of the binder. This pinion is also provided with the proper timing mechanism to throw it in and hold it out of gear. This timing mechanism consists of a projection, 68, forming a part of the pinion 66, a projection, 69, and two recesses, and 71, forming a part of the disk 65. \The projection 69 strikes the projection 68 and starts the pinion 66, and the recesses 70 and 71 make such rotation possible by admitting the corners of the square projection 68. As the disk 65 is rotated by the pinion 72 the friction-roller 63 rides on that part of theinternal rim-cam marked 73, and the knotter remains open, as shown, until said friction-roller leaves said cam 73 and is forced by the spring 64 to ride on that part marked 74, when the tongue 57 will close upon the hook' 56. As the tongue 57 closes upon the-hook 56 the knotter will be passing the ends of the around the shank of the hook 56, and thereby obviate undue strain upon the cord. As the knotter is completing its revolution to form the loop of the knot thecutter and gripper 45 45 receive a longitudinal movement outwardly through the agency of a cam, 79, formed upon the disk 80, a spring-rod, 81, a rod, 82, and a pivoted lever, 83, provided with a friction-roller, S4. The rod 81 is provided with a collar, 85, and a spring, 36, by which means the cutter and gripper 45 45 will be quickly returned for the purpose of cutting the band trom the supply and obtaining a new hold upon the supply portion. The rod 81 is fitted with a cone-shaped recess and the rod 82 with a cone-shaped point, which permits the rod 81 to revolve independentof the rod 82. The loop of the knot having been formed around the shank of the hook 56 in the manner above specified, and the two ends of the hand secured between the hook 56 and pivoted tongue 57, it only remains for the loop of the knot to he slipped from the hook 56 over the ends held by said hook, and the knot will be complete. To this end we use a horizontal rod, 87, which rides over a portion, 2, of the cast frame 2 and receives a longitudinal motion from a pivoted lever, 88. The lever 88 receives its motion from a cam, 73, formed upon the disk 65, and a rod, 89, provided with a friction-roller, 90. The rod 37 at its stripping end has raised ears 9], which fit loosely around the book 56, whereby the loop of the cord is removed from the book 56 57 to the ends held by said hook, and the knot is complete, and the cam 7 3'again raises the roller 63 and the ends of the band will drop from between the hook 56 and tongue 57, and, the friction-roller '90 having left the cam 73, a spring, 92, will force the stripper to its place of rest, as shown by Fig. 11 ot' the drawings. The compressor 3 will now open away from the sheaf, and the binding-arm 42 again descends to its position of rest, and the ejector 93, moving upward while the bindingarm moves downward, will remove the bound sheaf from the binding-table. The ejector is actuated by a toothed sector, 43, gearing into a loose pinion, 94, to which a spring-pallet, 96, is firmly secured, and arranged to engage with a ratchet-wheel, 95, fixed on the shaft 97, in such amanner as to cause said ratchet-wheel to remain at rest during the upward stroke of loosely upon the shaft 97 in order to run idle during the upward stroke of the sector 43.

The compressor 3 is actuated by a pinion, 101, fitting loosely onthe shaft 41 and on arm 102, fast to the shaft 33, the two being connected by a rod, 103.

The main wheel 25 isprovided with a smooth rim, 104, upon which a curved extension, 105, of the pinion 101 rides until it comes to a gap, 106, when a projection at the commencement of said gap strikes the curved piece 105, and the gap permits the curved piece to move and the pinion 105 to come intomesh with the main wheel 25 and make a full revolution before the curved piece 105 strikes the gap 106 and again engages with the rim 101. The pinion 72 is timed and revolved in precisely the same manner by the rim 107, curved projection 10S, gaps 109 110.

The connecting-rod 103 is provided with a movable head, 111, fitting into a. slide in the arm 102,.and a spring, 112, to permit the arm 102 to make a limited movement independent of the connecting rod103. Thislimited movement suffices to throw the roller,35 out of the recess formed in the end of the cam 34 to the even surface of the cam 34, and thereby throw the movable teeth 26 into mesh with the pinion 27. As the compressor-arm comes to rest during the formation of another sheaf the roller 35 again takes its place in the recess of the cam 34 and the spring-bolt 38 comes into the path of the inclined projection 31, which is fast to the movable teeth 26, and the teeth 26 are raised so as to disconnect the wheel 25 from the pinion 27.

The knotter proper is supported in a brack-' et, 113, made fast to the frame 2 in any suitable manner. v
